Shrub rose plant named ‘Chewnicebell’

ABSTRACT

A new and distinct cultivar of Rose plant named ‘Chewnicebell’, characterized by its upright, somewhat outwardly spreading and mounding plant habit; glossy green-colored leaves; freely branching growth habit; freely flowering habit; large light pink and yellow-colored flowers; resistance to Black Spot; and good garden performance.

Botanical designation: Rosa hybrida.

Cultivar denomination: ‘CHEWNICEBELL’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct Rose plant, botanically known as Rosa hybrida, commercially used as an ornamental Shrub Rose and hereinafter referred to by the name ‘Chewnicebell’.

The new Rose plant is a product of a planned breeding program conducted by the Inventor in Newport, Shropshire, United Kingdom. The objective of the breeding program was to develop new uniform and disease-resistant shrub Rose plants with large and attractive flowers.

The new Rose plant originated from a cross-pollination made by the Inventor in June, 1998 of Rosa hybrida ‘Pandemonium’, not patented, as the female, or seed, parent with Rosa hybrida ‘Scrivbell’, not patented, as the male, or pollen, parent. The new Rose plant was discovered and selected by the Inventor in 2004 as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Newport, Shropshire, United Kingdom.

Asexual reproduction of the new Rose plant by softwood cuttings at Newport, Shropshire, United Kingdom since 2004 has shown that the unique features of this new Rose plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Chewnicebell’. These characteristics in combination distinguish ‘Chewnicebell’ as a new and distinct Rose plant:

-   -   1. Upright, somewhat outwardly spreading and mounding plant         habit.     -   2. Glossy green-colored leaves.     -   3. Freely branching growth habit.     -   4. Freely flowering habit.     -   5. Large light pink and yellow-colored flowers.     -   6. Resistant to Black Spot (Diplocarpon rosae).     -   7. Good garden performance.

Plants of the new Rose differ from plants of the female parent, ‘Pandemonium’, in the following characteristics:

-   -   1. Plants of the new Rose are not as fragrant as plants of         ‘Pandemonium’.     -   2. Plants of the new Rose and ‘Pandemonium’ differ in flower         color as plants of ‘Pandemonium’ have striped orange and         yellow-colored flowers.     -   3. Plants of the new Rose are more resistant to Black Spot than         plants of ‘Pandemonium’.

Plants of the new Rose differ from plants of the male parent, ‘Scrivbell’, in the following characteristics:

-   -   1. Flowers of plants of the new Rose have more petals than         flowers of plants of ‘Scrivbell’.     -   2. Flowers of plants of the new Rose are not as fragrant as         flowers of plants of ‘Scrivbell’.     -   3. Plants of the new Rose and ‘Scrivbell’ differ in flower color         as plants of ‘Scrivbell’ have pink and white-colored flowers.     -   4. Plants of the new Rose are more resistant to Black Spot than         plants of ‘Scrivbell’.

Plants of the new Rose can be compared to plants of the Rosa hybrida ‘Chewhocan’, disclosed in U.S. Plant patent application Ser. No. 13/998,221. Plants of the new Rose differ primarily from plants of ‘Chewhocan’ in flower color as flowers of plants of ‘Chewhocan’ are clear yellow in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Rose plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Rose plant.

The photograph comprises a top perspective view of a typical plant of ‘Chewnicebell’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

Plants of the new Rose have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype. The aforementioned photograph, following observations and measurements describe plants grown in two-gallon containers during the summer in an outdoor nursery in Grand Haven, Mich. and under cultural practices typical of commercial Rose production. Plants were two years old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
